In the VVT process, the ventilator is checked for:
• System alarm – audio
• Patient pressure measurement and pressure performance
• Blower pressure measurement
• Transducer tubes leak
• Motor speed measurement
• Two solenoid valves
• Solenoid safety release mechanism
• Flow performance and flow zeroing accuracy
• Watchdog safety device
The user specifies two pressure values, while the patient circuit is con-
nected to a manometer. After the user dials in the first pressure value,
the blower increases the pressure and the user dials in the second
pressure value.
The values will be used to calibrate the pressure sensor:

This option runs a series of tests that check that all solenoids used in the
device are working properly. The user is instructed to place an RP20
resistance connector on the transducer. After confirmation the ventilator
starts running the tests.
